The FortiWeb appliance discloses the SNMP version 3 user’s password. The web page displayed by the appliance contains the password in clear text.
Thus, an administrator with at least a read-only access would be able to retrieve it.
To obtain this password, just navigate in the administration panel : system -> config -> SNMP -> edit SNMPv3 user.
Reading the html source code of the page reveals the password of the SNMP user.
